Unable to activate write_http collectd plugin

Issue

• We were asked from the monitoring to activate the write_http collect plugin.

• We added the following lines to our already working collectd configuration:

   CollectdExtraPlugins:
     - write_http
  ExtraConfig:
    collectd::plugin::write_http::nodes: "example" 
    collectd::plugin::write_http::urls: "http://netcoolbddlab01.oss.timbrasil.com.br"

• However, when collectd container tries to start we see the following error in the logs:

[2020-01-24 13:33:37] plugin_load: Could not find plugin "write_http" in /usr/lib64/collectd

• We have check and the rpm packet collectd-write_http-5.8.1-4.el7ost.x86_64 is installed in the servers:
